Application filed February 12, 1921. srial No. 444,484.

To allwhom it may. comm:

Be it known that EDWIN B; ALMSTRUM, a citizen of the United States, residing at Grand Island, in thefcounty of Hall and State of Nebraska, has invented certain new and useful Improvements in Chip-Catchers fication, reference being had to the accompanying drawings.

This invention relates to. a workmans protecting 'deviceand particularlyto a device to prevent damage by flying chips.

Numerous accidentsare cause each year by pieces or chips of flyin steel from tools caused by the breaking of the edge of the tool when subjected to a blow. The steel thus separated from the'tool is pro'ected with great force and in view thereo ously. injures the workman that it strikes.

It is therefore an object of the invention to provide novel means which protects the workman from suchinjury without requiring the workman to wear any device for the protection of the body such as goggles, etc.

Astill further object of the invention is to provide a device of this character capable of being applied to the end of a tool adapted to receive the force of a blow so that in case the tool is chipped, the separated particles of steel will be caught by the device. j

A still further object of the invention is to provide a device of this character which also protects the edge of the tool to a great extent bypreventing the edge of the tool from receiving the direct force ing blow.

A still further object of the invention is to provide a device of this character adapted to surround the blow receiving end of a tool and so positioned that it does not interfere with the contact of a hammer or like power implement with the end of the tool.

With the above and other objects in view,

of a glancthe invention consists in the improved construction and arrangement of the different parts to be hereinafter more particularly described, fully claimed and illustrated in the accompanying drawings, in which Figure 1 is a perspective and longitudinal sectional view of the chip catcher constructed in accordance with an embodiment of the invention.

Fig. 2 is anelevation and sectional View showing the catcher applied to one form of tool.

seri;

Fi 3 is an elevation and sectional View showingthc catcher applied to another form of tool.

f Fig. 4 is a sectional view of another form of the protector applied to a tapered end tool. j

Referring to the drawings, 5 designates a protector or chip catcher constructed from pliable rubber orlike flexible material, said protector being tubular. The outer surface of the sleeve istapered longitudinally so as "to perm t the small end 6 to readily conform to'the contour of a tool while the broad end 7 is of a thickness to prevent piercing thereof by a metal. chip.

In Fig. 2, the protector is shown as applied to a machinist hammer, the end 6 of the protector being adapted to conform to the shape of the hammer head. In this way the entire side surface of the hammer is protected. In Fig. 3, the sleeve is shown applied to a sledge hammer, the flexibility of the protector permitting the same to conform to the various sides of the hammer head. It will be noted that the end 7 is disposed fiush with the end of the tool. or in other words, flush with the striking face of the hammer. In this way, the protector does not interfere with the force of the blow delivered by the hammer, and in View of the fact that the end 7 is the only portion of the device which would be liable to come in contact with the head of the tool being struck, the force of the blow will slightly compress said end so that no resistance is offered. At the same time should the hammer strike an object in such a way as to chip the edge of the hammer, the particles of steel will be caught by the protector and held between the same" and the head of the hammer thereby preventing the chip from being projected and preventing considerable damage.

In Fig. a another form of the invention is shown. This form consists in enlarging the end 7 to provide a head 8, and constructing tion to this the bead 8 assists the end 7 in conforming to the tapered end so that it is impossible for any particle of metal that is separated from the tool to leave the tool after being'severed. In this form of the in- I vention similar to the form first described;

the end 7 is disposed flush with the end of the tool adapted to receive the blow so that contact of the power implement or tool with the end of the tool provided with the protector i's'notsinterfered with. In view of the flexibility of the protector, there is no danger of. the same becoming accidentally disengaged from the tool as it is not subj ected to any strain. If desired, glue or like adhesive material may be used to secure the sleeve to the tool.

What is claimed is l. A chip catching device for tools C0111- prising -a sleeve of pliable rubber adapted to be engaged ,upon and to conform to the contour of the sides of a blow receiving or delivering end of a tool, said sleeve having" a bore of uniform diameter and being externally tapered whereby its wall will be wedge shaped in longitudinal section, the thick end being designed to be flush with the end of the tool and the thin end possessing greater pliability whereby to automatically conform to the tool.

2. A chip catcher for tools consisting of a sleeve formed from pliable rubber and adapted to conform to the contour of the sides of a blow receiving or delivering end s of a tool, said sleeve being tapered longitudinally, the broad end of said sleeve being disposed flush with said end of the tool.

In testimony whereof I hereunto afiix my signature.
